From my point of view

I had been feeling lately that my eye sight was getting poorer and poorer.

 I thought it could be that I had a cataract in my right eye or that my lenses were too dirty and scratched.

I went to the optician and ... problem solved!

He said that lenses in my glasses had deteriorated very much. It was as if the different layers of glass that form the lenses had moved and had created a cataract, yes, but in the lenses; not in my eyes!!

New glasses in ten days!
